CAUTION
.Be sure to carry the Intelligent Key
with you when operating the vehicle.
. Never leave the Intelligent Key in the
vehicle when you leave the vehicle.
The Intelligent Key is always communicating
with the vehicle as it receives radio waves.
The Intelligent Key system transmits weak
radio waves. Environmental conditions may
interfere with the operation of the Intelligent
Key system under the following operating
conditions.
. When operating near a location where
strong radio waves are transmitted, such
as a TV tower, power station and broad-
casting station.
. When in possession of wireless equip-
ment, such as a cellular telephone,
transceiver, and CB radio.
. When the Intelligent Key is in contact
with or covered by metallic materials.
. When any type of radio wave remote
control is used nearby.
. When the Intelligent Key is placed near
an electric appliance such as a personal
computer. .
When the vehicle is parked near a parking
meter.
In such cases, correct the operating condi-
tions before using the Intelligent Key func-
tion or use the mechanical key.
Although the life of the battery varies
depending on the operating conditions, the
battery’s life is approximately 2 years. If the
battery is discharged, replace it with a new
one.
When the Intelligent Key battery is almost
discharged, see “Intelligent Key battery dis-
charge” (P.5-14) to start the engine.
Since the Intelligent Key is continuously
receiving radio waves, if the key is left near
equipment which transmits strong radio
waves, such as signals from a TV and
personal computer, the battery life may
become shorter.
For information regarding replacement of a
battery, see “Intelligent Key battery replace-
ment” (P.8-19).
As many as 4 Intelligent Keys can be
registered and used with one vehicle. For
information about the purchase and use of
additional Intelligent Keys, contact an
INFINITI retailer.
CAUTION
. Do not allow the Intelligent Key,
which contains electrical compo-
nents, to come into contact with
water or salt water. This could affect
the system function.
. Do not drop the Intelligent Key.
. Do not strike the Intelligent Key
sharply against another object.
. Do not change or modify the Intelli-
gent Key.
. Wetting may damage the Intelligent
Key. If the Intelligent Key gets wet,
immediately wipe until it is comple-
tely dry.
. Do not place the Intelligent Key for
an extended period in an area where
temperatures exceed 140°F (60°C).
. If the outside temperature is below
14°F (−10°C), the battery of the
Intelligent Key may not function
properly.
. Do not attach the Intelligent Key
with a key holder that contains a
magnet.
. Do not place the Intelligent Key near
equipment that produces a magnetic
field, such as a TV, audio equipment

INTELLIGENT KEY OPERATING
RANGE
The Intelligent Key functions can only be
used when the Intelligent Key is within the
specified operating range from the one
touch unlock sensor/door request switch
and trunk open request switch.
When the Intelligent Key battery is dis-
charged or strong radio waves are present
near the operating location, the Intelligent
Key system’s operating range becomes nar-
rower, and the Intelligent Key may not
function properly.
The operating range is within 31.50 in (80
cm) from each one touch unlock sensor/door handle request switch
and trunk open
request switch.
If the Intelligent Key is too close to the door
glass, handle or rear bumper, the one touch
unlock sensor and request switches may not
function.
When the Intelligent Key is within the
operating range, it is possible for anyone
who does not carry the Intelligent Key to use
the one touch unlock sensor or request
switches to lock or unlock the doors and
open the trunk lid.

Other conditions can affect the performance
of the Intelligent Key transmitter. See “In-
telligent Key system” (P.3-6) for additional
information.
REMOTE ENGINE START OPER-
ATING RANGE
The remote engine start function can only be
used when the Intelligent Key is within the
specified operating range from the vehicle.
When the Intelligent Key battery is dis-
charged or other strong radio wave sources
are present near the operating location, the
Intelligent Key operating range becomes
narrower, and the Intelligent Key may not
function properly.
The remote engine start operating range is
approximately 197 ft (60 m) from the
vehicle.
REMOTE STARTING THE ENGINE
To use the remote start function to start the
engine, perform the following:
1. Aim the Intelligent Key at the vehicle.
2. Push the LOCK
button to lock all
doors.
3. Within 5 seconds push and hold the remote engine start
button until
the turn signal lights flash and the tail lights illuminate. If the vehicle is not
within view, push and hold the remote
engine start
button for at least 2
seconds.
The following events will occur when the
engine starts:
. The front parking lights will turn on and
remain on as long as the engine is
running.
. The doors will be locked and the air
conditioner system may turn on.
. The engine will continue to run for about
10 minutes. Repeat the steps to extend
the time for an additional 10 minutes.
See “Extending engine run time” (P.3-
20).
. The rear window glass and outside mirror
defroster may turn on automatically
when the outside air temperature, the
interior temperature and the engine
coolant temperature are low.
Depress and hold the brake pedal, then place
the ignition switch in the ON position before
driving. For further instructions, see “Driving
the vehicle” (P.5-16).
EXTENDING ENGINE RUN TIME
The remote engine start function can be
extended one time by performing the steps
listed in “Remote starting the engine” (P.3-
20). Run time will be calculated as follows:
. The first 10 minute run time will start
when the remote engine start function is
performed.
. The second 10 minutes will start imme-
diately when the remote engine start
function is performed. For example, if
the engine has been running for 5
minutes, and 10 minutes are added, the
engine will run for a total of 15 minutes.
. Extending engine run time will count
towards the two remote engine start
limit.
A maximum of two remote engine starts, or
a single start with an extension, are allowed
between ignition cycles.
The ignition switch must be cycled to the ON
position and then back to the OFF position
before the remote engine start procedure
can be used again.

To return the steering wheel to the normal
position, stop the vehicle in a safe location
and stop operating the steering wheel. Then
drive the vehicle for a short period of time.
Condition B
. When the steering wheel is operated
repeatedly or continuously while parking
or driving at a very low speed. In this
case, the power assist for the steering
wheel will be reduced.
To return the steering wheel to the normal
position, stop the vehicle in a safe location
and wait for a period of time, without
operating the steering wheel, until the
temperature of Direct Adaptive Steering
cools down. Avoid repeated steering wheel
operations that could cause Direct Adaptive
Steering to overheat.
When the vehicle is tested on the 2-wheel
dynamometer, the power steering warning
light may illuminate. To turn off the power
steering warning light, stop the vehicle in a
safe location, turn the engine off, restart the
engine, and then drive the vehicle for a
period of time.
The following conditions do not indicate a
malfunction of Direct Adaptive Steering.
. You may notice wider steering play when
the ignition switch is in the OFF or ACC
position compared to when it is in the ON position.
. After the engine is started, the steering
wheel may turn slightly even when
driving on a straight road. To return to
the normal position, drive the vehicle on
a straight road for a period of time.
. After the engine is started, the steering
wheel may move if the steering wheel
was turned to the fully locked position
while the ignition switch was in the OFF
position.
. After the vehicle is tested on the 4-wheel
dynamometer, the steering wheel may
turn slightly even when driving on a
straight road. To return the steering
wheel to the normal position, drive the
vehicle on a straight road for a period of
time.
You may hear a noise under the following
conditions. However, this is not a malfunc-
tion.
. When the engine is started or stopped.
. When the steering wheel is turned in the
full lock position.BRAKING PRECAUTIONS
The brake system has two separate hydrau-
lic circuits. If one circuit malfunctions, you
will still have braking at two wheels.
Vacuum assisted brakes
The brake booster aids braking by using
engine vacuum. If the engine stops, you can
stop the vehicle by depressing the brake
pedal. However, greater foot pressure on
the brake pedal will be required to stop the
vehicle and the stopping distance will be
longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will cause overheating of
the brakes, wearing out the brake and pads
faster and reduce gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going
down a slope or long grade. Overheated
brakes may reduce braking performance and
could result in loss of vehicle control.
WARNING
. While driving on a slippery surface,
be careful when braking, accelerating

6. Keep the engine speed of the boostervehicleat about 2,000 rpm, and start
the engine of the vehicle being jump
started
.
CAUTION
Do not keep the starter motor engaged
for more than 10 seconds. If the engine
does not start right away, push the
ignition switch to the OFF position and
wait 10 seconds before trying again.
7. After starting your engine, carefully disconnect the negative cable and then
the positive cable (
???).
8. Replace the vent caps (if so equipped). Be sure to dispose of the cloth used to
cover the vent holes as it may be
contaminated with corrosive acid.
9. Put the battery cover and the engine cover back to the original location. Do not attempt to start the engine by
pushing.
CAUTION
.
Automatic Transmission (AT) models
cannot be push-started or tow-
started. Attempting to do so may
cause transmission damage.
. Three-way catalyst equipped models
should not be started by pushing
since the three-way catalyst may be
damaged.
. Never try to start the vehicle by
towing it; when the engine starts,
the forward surge could cause the
vehicle to collide with the tow vehi-
cle.
CAUTION
.Do not continue to drive if your
vehicle overheats. Doing so could
cause engine damage or a vehicle fire.
. To avoid the danger of being scalded,
never remove the radiator cap while
the engine is still hot. When the
radiator cap is removed, pressurized
hot water will spurt out, possibly
causing serious injury.
. Do not open the hood if steam is
coming out.
If your vehicle is overheating (indicated by an
extremely high temperature gauge reading),
or if you feel a lack of engine power, detect
abnormal noise, etc., take the following
steps:
1. Move the vehicle safely off the road, apply the parking brake and move the
shift lever to the P (Park) position.
Do not stop the engine.
2. Turn off the climate control. Open all the windows, move the heater or air condi-
tioner temperature control to maximum
hot and fan control to high speed.
3. If engine overheating is caused by climb- ing a long hill on a hot day, run the engine
